Question

A solution's pH is given by the function p(t) =

-log(t), where t is the hydronium ion concentration, in moles per liter.
A sample of coffee has
a pH of 3.0. What is the approximate ion concentration of the sample?

Answer 1

`t=(1)/(1000) \ mole/liter`

Explanation:

p(t) = -log(t)

3.0 = -¹⁰log(t)

-3.0 = ¹⁰log(t)

`\boxed{^alog\ b =c \implies a^c=b}`

t = 10⁻³

`t=(1)/(1000) \ mole/liter`
